'''Elliott O'Donnell''' (27 February 1872 – 8 May 1965) was an author known primarily for his books about ghosts. He claimed to have seen a ghost, described as an elemental figure covered with spots, when he was five years old. He also claimed to have been strangled
by a mysterious phantom in Dublin
(however, no permanent effect would seem to have been suffered).
